a phrase usually used to annoy and stop preachers from spreading the word of god by saying everyone goes to hell. most often associated with the youtuber "Piscator11" when he first exclamed that a woman aint got no pancake mix

One day, a Christian extremist fundie lady made the mistake of preaching to a group of students, and threatening them with hell. One of the students had enough of her non-sense and decided to do something quite strange and unpredictable. He approached her and shouted "You ain't got no pancake mix!" and other variations of the phrase repeatedly. Every time she opened her mouth, he would interrupt her, similar to Kanye West.

The reason for him deciding to say that is unknown. One can assume that he simply chose the phrase at random. Whatever the reason for him saying it, he managed to upset the lady. Lulz ensued.

Absurd, stream-of-consciousness phrase used by Zach Galifianakis in a stand-up routine in Luna Park, West Hollywood, California in January 1999. The term has come to be a broader vehicle for closing an argument or putting a speaker off balance. This use can be viewed on YouTube by searching for "Zach Galifanakis Luna Park 1999". The line occurs about about 5:31 into the routine.

From Zach Glifianakis' 1999 Luna Park, West Hollywood comedy routine:

"Why do I sit around Indian-style on my hardwood floor, yelling out to myself, 'You ain't got no pancake mix!'?"
